IMPRVEMENT IN SEC'URING' VENEERS To WCD.

The Schedule referred to in theseLetters Patent and making part of thename To all persons to whom these presents Ashall come".-

Be it known that I, WILLAM H. KNIGHT, of Boston Highlands, in the countyof Suffolk and State of Massachusetts, have invented a new and usefulMode of Applying and Securing Veneers to Surfaces; and that thefollowing description, taken' in connection with the accompanyingdrawing hereinafter referred to, formsA a full and completespecification of the same.

The present invention consists in applying and securing veneers tosurfaces of wood, 85o., by expanding the wood or material that'istoreceive a veneer, in combination with contracting the veneer, so that,when the two are placed together, and secured by glue or othersnitableadhcsive matriaL-aud dried b'y the then contraction of thepreviously-expanded wood or. base, the grain or fibers of the veneerarebrought most closely together, and the pores thereof tightened,preventing checking, so termed, that is, the cracking or breaking awayof the veneer when in use.

It also consists, in combination with the above, in veneering thecases'or bo'dies of piano-fortes, more particularly by rst applying andsecuring the v cner to a comparatively thin picce'of hoard along itslength, and in then applying such combined stlip to the body or case, inthe ordinary manner now practiced of securing a veneer direct.

In the accompanying drawing this invention is illustrated. K

Figure l is an edge view of a veneer-receiving wood.

.Figure 2, a section of a veneer and a wood-base, the one secured to theother.

Figure 3, an edge View of 'the veneer and wood-base, shown in iig. 2,applied and secured to a block of wood, with the said wood-base incontact.

A, in the drawing, represents a veneer; Y

B, a wood-base, to which said veneer is applied and secured; and

C, a block to which the :combinedyencer A and wood-base B are secured,with the wood-baseA B in contact therewith.

In carrying out this invention, I expand the wood B, which is to receivethe veneer A, by subjecting the same to moist steam, orto moisture inany form, and then, having dried the vencer A by applying heat theretoof '1250*ll`ahrenheit, more or less, in any suitable manner, by placingit in a heated chamber, or

by arranging it to be acted upon by heat from a suitable heatingapparatus, the two are placed together; the veneer\ on the wood,`withglue or other suitable By thus expanding wood previous to receiving aiveneer, which has been to a greater or lesserextent dried 'andcontracted in the'drying of the two after being glued together, thefibers or grain of the veneer vare of a necessity drawn tightly andclosely together because of the greater contraction of the wood to whichsaid veneer is applied, thereby, asis obvious, prevent-` ing thetendency of the veneerto check in its after exposure to the-atmosphereby use.

In veneer-ing piano-forte cases, the wood composing which cannot beexpanded without detriment to they cases, the veneers are'applied by rstapplying and securing them to a comparatively thin piece of wood, andthen the combined strip attached to the case, in the ordinary manner ofgluing a veneer direct.

Having thus described' my invention,- I shall state my claim as follows:

What I claim is- 1. The mode herein described of applying. andr securingveneers, the same consisting in expanding the wood to receive theveneer, in combination with contracting the veneer, substantially asdescribed, for the purpose specied.

2. In veneering piano-forte cases', 85o., applying and securing theveneer iirst to a comparatively thin piece of wood, ,substantially asdescribed, and then applying and securing such combined strip to thecase..

The above specification of my invention signed by me this 25th day ofNovember', A. D. 1869. v
